Super I/O with LPC Interface with FIR and Consumer IR Support
General Description
The SMSC SIO1000 is a 3.3V PC 99, PC2001, and ACPI 2.0 compliant Super I/O Controller. The
SIO1000 implements the LPC interface, a pin reduced ISA interface which provides the same or better
performance as the ISA/X-bus with a substantial savings in pins used. The part also includes 14 GPIO
pins.
The SIO1000 incorporates a 16C550A compatible UART and one Multi-Mode parallel port with
ChiProtect circuitry plus EPP and ECP support. The SIO1000 does not require any external filter
components, is easy to use and offers lower system cost and reduced board area.
The SIO1000 offers a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI
CLKRUN# support, relocatable configuration ports, and three DMA channel options.
The on-chip UART is compatible with the 16C550A. There is a dedicated Serial Infrared interface
UART, which complies with IrDA v1.2 (Fast IR), HPSIR, and ASKIR formats (used by Sharp and other
PDAs), as well as Consumer IR. There is a second dedicated Consumer Infrared interface, which
complies with NEC PPM and Phillips RC5 formats.
The parallel port is compatible with IBM PC/AT architectures, as well as IEEE 1284 EPP and ECP.
The parallel port ChiProtect circuitry prevents damage caused by an attached powered printer when
the SIO1000 is not powered.
The SIO1000 features Software Configurable Logic (SCL) for ease of use. SCL allows programmable
system configuration of key functions such as the parallel port and UART.
The SIO1000 supports the ISA Plug-and-Play Standard register set (Version 1.0a) and provides the
recommended functionality to support Windows operating systems, PC99, and PC2001. The I/O
Address, DMA Channel, and Hardware IRQ of each device in the SIO1000 may be reprogrammed
through the internal configuration registers. There are multiple I/O address location options, a
Serialized IRQ interface, and three DMA channels.
